Is any hardware mining investment made today going to be profitable?

...according to this apparently not:  http://mining.thegenesisblock.com/

Select any manufacturer/product and a sensible start to your mining date (based on speculative vendor shipment dates) and it appears that nothing is going to turn you a profit (actually not tried them all but I have most). 

Does anybody consider this calculator to be accurate? If it is accurate then why are people falling over themselves to buy hardware that won't even allow them to break even?

Any insight appreciated.

Thanks

Anybody? Quite surprised nobody has answered.

Profitability probability range from fair to none. This subject has been debated in many threads. Do some research on the forum.

A calculator is just a tool it isn't magical.  What matters is how fast difficulty goes up.  Nobody knows for sure.  However miners are very expensive and the profits decline rapidly.  If you are thinking about buying today you are essentially getting in at the end of the line.  Very likely you will lose money.

transfinite para-magnetic states can be simulated on the hardware layer with the right library cores. in this fashion, one can simulate a massively parallel cluster with just enough operating system with one client making calls over the stratum proxy. next time you log into your mining pool, check the hashes/second versus bitcoin output for a couple of users and you'll start to notice that there's no true correlation.

satoshi's original paper called for a minimal structure. the minimal unix build contains most of the compiler toolsets required to be able to solve for headers. even the fact that a user makes client calls over RPC is merely a rewrite of the BitTorrent protocols.

To me, it's a mix bag. Since difficulty can change randomly and/or depending how many people mine. It mostly depends on hardware and power costs for GPU mining. I only $3 to $5 gross daily average, some days more, net I $2 to $4 a day. I only can afford at the moment the rig I'm running with 2 HD 5870's and a HD 5850, about 1000~1200 Kh/s. My power cost per Kw/h is $0.13 in my area. Everyone favors the HD 7950, as it is the best power to hash rate to cost value, unless you can get a hold of a HD 7990 for a decent deal. Most people run 3 to 4 HD 7950 per rig. I'd like to do that too, but money is an issue with me lately.
